Make it possible to use explicit placement
(although not hooked up with a user-space interface yet)
and relax the single framebuffer limit to only apply to implicit placement.

It isn't used for anything. Replace with an active bool.

Also make a couple of functions return void instead of int
since their return value wasn't checked anyway.

Make sure we null the display private, make sure we catch and
handle vblank failing to init and don't call vblank_cleanup if
we haven't initialized the display system.

Add / fix some function comments.
Don't move out an fbdev framebuffer when unused. Just unpin.
Only have a single function that computes a SVGAGuestPtr from the buffer's
current placement, and make it more versatile by accepting a
struct ttm_buffer_object
